January is a popular month for Antarctic cruises, with most areas accessible and voyages down to the Antarctic Circle possible, due to the breakup of sea ice during the peak summer period. The ice in the Ross Sea melts and breaks away, providing a short window of time when you can visit the historic huts of explorers Sir Ernest Shackleton and Robert Falcon Scott.
Temperatures rise to 15 degrees Celsius, making conditions very comfortable for cruising and travelling ashore to the Antarctic mainland. Fluffy penguin chicks can be seen in the rookeries, as their stressed parents work hard to bring them food; whilst giant humpbacks can be spotted in the feeding grounds, feasting on krill.
